A semiconductor package includes a first semiconductor package including a core member having a through-hole, a first semiconductor chip disposed in the through-hole and having an active surface with a connection pad disposed thereon, a first encapsulant for encapsulating at least a portion of the first semiconductor chip, and a connection member disposed on the active surface of the first semiconductor chip and including a redistribution layer electrically connected to the connection pad of the first semiconductor chip, a second semiconductor package disposed on the first semiconductor package and including a wiring substrate electrically connected to the connection member, at least one second semiconductor chip disposed on the wiring substrate, and a second encapsulant for encapsulating at least a portion of the second semiconductor chip, and a heat dissipation member covering a lateral surface of the second semiconductor package and exposing an upper surface of the second encapsulant.
